Description

The invention relates to a method for high-precision alignment of a quick-release cylinder on a machine-fixed reference surface and a quick-release cylinder used for performing the method with a cover-side anti-rotation device according to the preamble of the main claims.

With the DE 197 16 800 A1 is a quick-release cylinder of the type mentioned become known, in which a workpiece pallet with workpieces to be machined on the bottom is connected to a retractable nipple. The intake nipple is drawn into an associated receptacle of a quick-release cylinder and is locked there by means of balls.

The workpiece pallet is here attracted with associated stop edges and bearing surfaces on the top of the lid of the quick release cylinder and is to be set there correct position and high accuracy with respect to a machine-fixed reference surface.

However, the lid of the known device is mounted with simple hexagon socket screws on the housing of the quick release cylinder.

When machining workpieces in which a rotational load is applied to the workpiece pallet, it tends to twist in a horizontal plane on the lid. This is prevented by the corresponding stop edges between the workpiece pallet and the lid. An undesirable rotation of the workpiece pallet in relation to the cover of the quick release cylinder is thus prevented. However, in these load situations, the twisting forces exerted on the lid by the workpiece pallet may undesirably twist the lid relative to the fixed housing of the quick-release cylinder. As a result, the processing of arranged on the workpiece pallet workpieces is inaccurate.

The hexagon socket screws used in a known manner for connection between the cover and housing have a certain play in their recordings in the lid, which adversely affects the accuracy of the processing.

This causes (at high torque stresses between the lid and the fixed housing) that the hexagon socket screws are strangled and the lid unintentionally rotated to the fixed housing by a small amount of play.

According to DIN, for example, has the screw hole in the lid with respect to the screw a game of 1 millimeter and this game can not be compensated by the evenly distributed around the circumference arranged hexagon socket screws are tightened with high force. While this was attempted, it could happen that at higher torque loads, the frictional force between the lid and the housing was removed despite the strongly tightened Allen screws, which in turn undesirably rotated the lid relative to the stationary housing.

With correspondingly high torques, such as arise in particular when machining workpieces with roughing tools, it may additionally happen that the hexagon socket screws screwed into the associated mounting bores knock out.

Depending on the effect of the torque load, in this case a rotation of the cover to stop either in right or left turn pass so long until the screws are present at the corresponding inner walls of the screw holes.

The DE 100 50 996 A1 discloses a quick release cylinder, wherein the lid is screwed via an external thread with an internal thread on the housing.

The invention has for its object to provide a method for high-precision alignment of quick-release cylinders to a machine-fixed reference surface and a device operating according to the method in such a way that the quick-release cylinder do not twist undesirably even when exposed to high torsional forces on the lid to the machine-fixed reference surface or tilt.

In particular, the connection between a cover of a quick-release cylinder and the housing of this quick-release cylinder should be designed so that this connection is highly accurate and absolutely secure against rotation and can transmit high torsional forces without play.

To solve the problem, the method is characterized by the technical teaching of claim 1.

An apparatus for carrying out the method is characterized by the technical teaching of claim 4.

It is essential that between the lid and the housing first to the se known and distributed around the circumference arranged screws are screwed in and further that at least one point on the circumference between the housing and the cover a backlash-free anti-rotation connection is arranged.

With the given technical teaching, there is now the significant advantage that the aforementioned game of twisting between the screws, which engage in threaded holes in the housing and in the lid, thereby avoiding that at least one point on the circumference between the lid and the housing an additional play-free anti-rotation connection is arranged.

With the given technical teaching, therefore, there is the advantage that due to this backlash-free connection now even with the action of high torsional torques between the cover and housing are received in perfect manner by the backlash-free anti-rotation connection and are no longer transferred to the screws that might otherwise turn down.

In a first preferred embodiment of the invention, it is provided that the play-free anti-rotation connection consists of a dowel pin connection, which is arranged without clearance and high-load transfer between the lid and the housing.

In such quick-release cylinders, the problem is that you must position the lid of the quick release cylinder with high precision in a processing tower or in a machine table to ensure that the rotatably and highly accurate patched on the lid workpiece pallet is precisely aligned.

It is therefore not important according to the invention that the housing of the quick release cylinder itself is aligned with high precision to a machine table or other reference surface, but the invention has recognized that it is sufficient to align the lid of the quick release cylinder with high accuracy, without affecting the orientation of associated housing arrives.

It only needs to be ensured that the housing is firmly and immovably mounted on a machine table, a clamping plate or a processing tower in such an orientation (mounting position) that a subsequent fine alignment of the lid on a machine-fixed reference edge is possible.

For highly accurate alignment of the lid of the quick release cylinder, it is accordingly necessary that the lid is arranged alignable on the top of the housing of the quick release cylinder. For this purpose, it is provided that the distributed evenly distributed on the circumference hexagon socket screws or shoulder screws are tightened hand-tight, so that the lid initially receives a preliminary orientation to the housing of the quick release cylinder. The side edges or the abutment edges of the cover are now accurately aligned with a dial indicator to form a reference surface, which is arranged, for example, on a processing tower or on a machine table.

In order now to set this once set and not to be changed orientation of the cover to the housing, the invention now provides that as an additional connection, the previously mentioned backlash-free anti-rotation connection is made.

The first embodiment of this play-free anti-rotation connection is the previously mentioned dowel pin connection, which consists essentially in that in each case at least one fitting bore is present in the housing of the quick release cylinder, in which a dowel pin is taken. By hammering the dowel pin into the fitting bore, there is a violent adaptation of the dowel pin to the bore and thus a backlash-free load transfer is ensured.

The dowel pin can have any shape in relation to this hole. For example, a round fitting bore can be used and, for example, the locating pin which is driven into this bore is also round-profiled. However, it can also be square or oval profiled, because it only matters that the dowel pin is free of play (possibly with material removal) recorded in this fitting bore.

The dowel pin then projects beyond the upper end face of the housing by a certain amount and engages in an associated bore in the inside of the cover.

This hole can be formed as a through hole or as a blind hole.

It is now important that the once set position of the lid - which is determined by the dial gauge and by tightening the aforementioned screws - is now fixed by the dowel pin engages the hole in the lid with play and that in between there The passport and the inside of the hole resulting gap now a curable adhesive is introduced. This adhesive should be highly load-transmitting, so that thus a high-load-carrying, backlash-free anti-rotation connection through the dowel pin, the adhesive and the assigned fitting bore is made in the housing of the quick release cylinder.

Thus, the backlash-free and highly accurate orientation of the lid to the outer reference surface is fixed and according to the invention, this position is now properly fixed with this backlash-free anti-rotation connection and no longer changeable.

Thus, even high torsional forces from the workpiece pallet on the lid are initially taken up by the play-free anti-rotation connection between the lid and the housing before these forces are transferred to the screw connections, which are still present in large numbers, which are thus deflected before being knocked out or twisted. or legal direction.

However, it is preferred according to the invention, if instead of a single backlash-free anti-rotation connection of the type mentioned above, the two are present. In this case, it is again preferred if these two play-free anti-rotation connections lie opposite one another diagonally with respect to the central center opening in the quick-release cylinder.

However, the invention is not limited to the arrangement of two diagonally opposite anti-rotation connections; It is also possible for more than two such compounds to be arranged diagonally opposite one another or else in pairs or in groups.

While the embodiment described above consists in that in the housing of the quick release cylinder a fitting bore is present, in which the dowel pin is hammered, it can also be provided in kinematic inversion, that on the underside of the cover such a fitting bore is arranged, in which Pass pin is hammered, the dowel pin is now set in an associated hole with excess in the housing by means of adhesive.

In addition, it is not necessary for the solution that the dowel pin is solid. It is also possible to use tube-shaped dowel pins or also dowel pins.

To disassemble the entire assembly, it is sufficient to solve the aforementioned screws all together and remove and by means of a punch, the fitting in the fitting hole dowel pin can be knocked out from the bottom of the housing ago.

Likewise, it is possible after loosening all screws, that the pressure chamber of the quick release cylinder is pressurized oil to squeeze the lid up. The pressure chamber acted upon with pressure oil is preferably formed between a surface of the lid and an associated surface of a piston of the ball lock in the quick-release cylinder, so that when the pressure chamber is acted upon, the lid is blown upwards.

In another embodiment of the invention, the dowel pin connection is additionally equipped with a drill sleeve. Here, the drill sleeve is glued so that the drill sleeve receives the dowel pin without play and high load, while on the opposite side in the housing, the aforementioned fitting hole is arranged, in which the dowel pin is driven forcibly.

For service purposes, the second-mentioned embodiment offers great advantages, because the cover can be easily removed upwards because the dowel pin then disengages from the drill sleeve without damaging or destroying the adhesive between the drill sleeve and the bore in the cover.

The invention is not limited to the fact that the play-free anti-rotation connection according to the invention is formed between the housing of the quick-release cylinder and the cover.

All the connections described above and below can also be made directly by placing the lid directly on a machine table or on a working table and fixing it there so that the entire quick-clamping cylinder is received in a corresponding recess in the machine table or in the processing tower. In this case, the housing "of the quick-release cylinder is formed by the inclusion in the machine table or the clamping plate or the processing tower.

Embodiments have been mentioned above, in which a dowel pin is glued either directly in a hole or with the interposition of a drill sleeve.

In two other embodiments of the invention, however, it is provided that instead of a dowel pin a screw (preferably a shoulder fitting screw) is glued directly into the bore, for which there are several different embodiments.

In the first embodiment it is provided that the shoulder fitting screw in a assigned threaded hole is screwed into the housing and sits by means of a centric fitting collar in an associated fitting hole in the housing. There, then, the shoulder fitting screw is kept free of play.

However, the bore in the lid has a play in relation to the outer circumference of the shoulder fitting screw and this hole is now according to the invention again filled with a hochlastübertragenden and curable adhesive, so that in this way a backlash-free and high-load-transmitting anti-rotation connection is created.

Instead of the aforementioned shoulder fitting screw can be used in a further embodiment, a simple Allen screw, which is glued both in their housing side and in their cover-side bore. It is therefore also a high-load-transfer adhesive bond with the aid of a simple hexagon socket screw, which is fitted in two mutually ordered parts (housing and cover) with high accuracy and clearance and then stuck.

The described embodiments have great advantages over the prior art. Although it is known to use in the connecting region between the housing and the lid so-called shoulder fitting screws. In these known embodiments, however, it has always been necessary for high-precision alignment to process both the cover of the quick-release cylinder and the machine table, the machine plate or the processing tower (as a receptacle for the quick-release cylinder) with a coordinate grinder. The central recess in the lid had to be centered exactly to the housing and this centering could only be done by the side edges of the lid were processed with a high-quality jig grinding machine.

Once this processing was completed, it had to be ensured that the threaded holes for the aforementioned threaded screws for fixing the lid on the housing were also centered with high precision to the center hole.

It is known to form the contour of the lid as a square. Starting from such a square shape, it was necessary to center the square lid with its central center recess to the central center recess of the clamping receptacle in the housing with high accuracy. In addition, care had to be taken to ensure that the threaded holes required to fix the cover on the housing were machined with the appropriate shoulder fitting screws. These multiple processing steps, which led to a very complex processing can now be avoided according to the invention.

According to the invention, it is sufficient hand-tight tighten the aforementioned screws for fixing the lid on the housing and align the lid using a dial gauge on the aforementioned reference surface on the machine table or on the processing tower. If the high accuracy alignment has been determined, then in the next step, the high load transfer, backlash-free anti-rotation lock is applied between the cover and the housing, which is then always maintained, even if high twisting forces are exerted on the cover from the side of the workpiece pallet.

The better clarification because it should be mentioned that after the high-precision alignment of the lid with only hand-tightened screws this once set position is fixed by the fact that the screws are tightened with high torque, so that a further displacement of the lid is no longer possible. Only then the inventive, backlash-free and high-load-transmitting anti-rotation connection is attached.

The subject of the present invention results not only from the subject matter of the individual claims, but also from the combination of the individual claims with each other.

All information and features disclosed in the documents, including the abstract, in particular the spatial design shown in the drawings, are claimed to be essential to the invention insofar as they are novel individually or in combination with respect to the prior art.

In the following, the invention will be explained in more detail with reference to drawings illustrating several execution paths. Here are from the drawings and their description further features essential to the invention and advantages of the invention.

In known manner, there is the quick release cylinder 36 to 1 essentially from an approximately cylindrical housing 1 , in its central inner recess 44 the ball lock for locking a retractable nipple 7 is arranged according to 7 at the bottom of a workpiece pallet 15 is attached.

The housing 1 is with the help of clamping claws 2 and associated screws 3 on a machine table, not shown 4 attached.

The intake nipple 7 grips through the central recess 44 in housing 1 through and also passes through another central recess 43 in the lid 6 ,

The lid has a ring collar on its underside 42 on, with which he is in the area of the central recess 44 in the case 1 is centered. The ring collar 42 engages in the press fit in the recess 44 in the case 1 one.

For fixing the lid 6 are according to 2 all around the lid evenly distributed a set of screws 8th arranged, which are formed as threaded screws. For this example, on 3 directed. According to 2 The screws can also be arranged in groups in pairs.

Through evenly tightening the screws 8th thus becomes the lid 6 in the central recess 44 with his waistband 42 retracted and fixed there centric. He is thus relatively secured against rotation in relation to the housing 1 attached.

It is important now that at the bottom of the lid 6 and on the associated front side 5 of the housing 1 now corresponding bearing forces arise, which by the strong tightening the groupwise arranged screw 8th arise.

Nevertheless, this connection is between lids 6 and the housing 1 in the area of the front side 5 not yet load-bearing enough.

According to 3 namely, on the lid a workpiece pallet 15 put on and this workpiece pallet is centered with a stop surface 22 at an associated stop edge 18 on the lid 6 , At the same time lies the workpiece pallet 15 with an outer counter surface 21 on the associated support surface 20 on the lid. Over the edges 18 . 22 and the mating surfaces 20 . 21 Thus, all forces are free of play from the workpiece pallet 15 on the lid 6 transfer.

But now, for example, by a corresponding workpiece machining the lid 6 in the direction of the arrows 13 claimed to turn, then the previously mentioned screws 8th also claimed to rotation and shearing, which leads to the disadvantages given in the general description part.

This is where the invention begins, which proposes an additional, high-load-transmitting, backlash-free anti-rotation connection, which in the embodiment shown from the dowel pin connection 9 consists.

At two diametrically opposite locations on the circumference of the housing 1 here are each passport holes 14 arranged, in each of which a dowel pin 10 is forcibly driven.

Instead of trained as blind holes fitting holes 14 can also assigned through holes 41 be used to by means of a suitable workpiece the dowel pin 10 to be able to drive out again for repair purposes, if the screws 8th previously solved.

It is important now that the high-precision determination of the lid 6 to an outside Reference surface on the machine table 4 The lid now by tightening the individual screws 8th is set so that he is no longer on the case 1 can be moved. At the same time, however, engages the upper side of the dowel pin 10 with game in an assigned hole 11 in the lid 6 and this game is now eliminated according to the invention with a curable and high-load-transfer adhesive or casting resin. This mass is poured there.

Instead of a thermosetting adhesive or a cast resin, other load-bearing bushes (or otherwise non-circular and irregular), or other elements capable of lining the irregular gap as completely as possible so that load transfer can take place over this material may be used. For example, pouring can also be done with lead or tin, which leads to the same result.

The important thing is that the dowel pin eccentric if necessary in the oversized bore 11 intervenes. This (eccentric) game is now eliminated by pouring, driving or filling with a suitable material to the extent that corresponding torsional forces of the lid 6 be transmitted via the backlash-free anti-rotation lock on the dowel pin and thus on the housing.

Instead of hardenable substances, for example, caulking can take place with a suitable material. The space can be filled with a tin wire, which is then distributed with a suitable impact tool, as well as a high-load-transmitting connection between the dowel pin and the associated hole 11 in the lid 6 to ensure.

In the general description part has also been noted that the arranged here in the lid connection between the dowel pin 10 and the hole 11 in kinematic reversal also in the housing 1 can be provided. All previously mentioned parts and connections can thus be in the housing 1 be made, which then in the lid 6 the pilot hole 14 with the dowel pin 10 is present and the bore in the housing lined with appropriate oversize, taped or poured out.

The 3 shows as another embodiment, that instead of pouring the bore 11 in the housing a Bohrbüchse 16 can be used. Here, according to the invention, the drill sleeve with a corresponding smaller measure in the oversize bearing bore 11 used and again the gap between the outer circumference of the drill sleeve 16 and the inner circumference of the bore 11 in the lid 6 lined, filled or closed in another way load transfer.

Advantage of this measure is that easy removal of the lid 6 from the case 1 is possible because when removing the screws 8th the lid can be easily lifted up because of the dowel pin 10 from the drill sleeve 16 from slipping. Dismantling the lid 6 without destroying the high-precision anti-twist protection is especially necessary for service and maintenance purposes.

The 4 and 5 show that it is not necessary that the cover with a separate housing 1 connected is. There it is shown that the quick-release cylinder, omitting the housing directly into an associated recess 17 in the machine table 4 or in a processing tower to be explained later 35 can be introduced.

Again, the same explanation applies that for this case either in the machine table 4 or in the processing tower 35 the assigned fitting hole 14 for driving in and setting the dowel pin 10 is provided.

The 6 and 7 show the bottom of the workpiece pallet 15 where it can be seen that the mentioned stop surfaces 22 are present in the region of a square recess, located at the aforementioned stop edges 18 of the lid 6 create load-transmitting.

At the same time are the counter surfaces 21 shown on the associated contact surfaces 20 resting on the cover load transfer.

The remaining surfaces at the bottom of the workpiece pallet 15 are not load-bearing, as indicated by the narrow (indicative of the distance) line in 3 is shown.

Instead of in 1 illustrated dowel pin connection 9 So can the in 4 illustrated dowel pin connection 19 with the described drill sleeve 16 be used in all installation situations, either in a housing 1 , in a machine table 4 or in a processing tower 35 ,

The 8th and 9 show two further embodiments of associated anti-rotation connections. At the anti-rotation connection after 8th becomes a so-called adhesive bond 29 used. There instead of a dowel pin 10 one or more shoulder fitting screws 23 used.

Each shoulder fitting screw is in an associated threaded hole 24 with a bolt 25 screwed in and has axially over a passband 31 on, the centric and load-transmitting at the assigned fitting bore 30 in the case 1 invests.

The resulting supernatant in the head area of the shoulder fitting screw 23 is with oversize in the assigned hole 11 in the lid 6 used.

The resulting gap 26 is now again with one of the previously described measures, but preferably with an adhesive 27 , filled out. This in turn results in a high load transmitting connection between the lid 6 and the housing 1 - or the machine table 4 over the shoulder fitting screw 23 - With the help of the play-free anti-rotation connection.

A similar representation applies to the in 9 illustrated adhesive bond 29 where it is shown that a simple hexagon socket screw 32 with glue 34 both in the threaded hole 24 in the case 1 or in the machine table 4 is fixed and beyond the supernatant in the lid 6 in the area of the bore 11 and the gap forming there 33 with glue 34 is filled.

So it is a both bolt side and head side completely glued hexagon socket screw 32 ,

The 10 and 11 show as a further embodiment of the installation of the invention quick-release cylinder 36 a so-called quick-release plate 45 , It is a larger plate in which at regular intervals (pitch) a variety of quick release cylinders 36 are installed.

This quick release plate 45 is by means of fasteners, not shown on a machine table 4 attached. It can, however, also on the surfaces of a processing tower 35 be attached.

Important in the embodiment according to 10 and 11 is that first the quick release plate 45 by means of the dial gauge 40 is aligned with respect to a machine-fixed reference surface, wherein the alignment takes place in two mutually perpendicular directions.

Of course, the invention provides that not only the orientation of one or more gauges is possible, but over all other known, including electronic, alignment.

After aligning the quick-release plate 45 to a machine-fixed reference surface now have the individual quick-release cylinder 36 , and whose lid relative to the quick-release plate 45 to be aligned.

For this it is sufficient, only the alignment, for example in the X direction by means of the dial gauge 37 for all lids 6 because the lids themselves are machined with high precision and their contours correspond exactly (preferably) to a square.

By means of the dial gauge 37 this is for example moved in a horizontal direction, so with slightly tightened screws 8th all lids 6 all in-line quick release cylinder 36 align. After alignment, the screws 8th tightened tight because the lids 6 so now highly accurate and correct position are fixed and only then the inventive, backlash-free anti-rotation connections are attached.

At every lid 6 on each quick release cylinder 36 The resulting gap in the bore is then poured, lined or caulked by means of a tube, whereby the mentioned backlash-free, high-load-transmitting anti-rotation connection is created.

Here, the anti-rotation can be done either by pouring the outer circumference of the drill sleeve or by pouring the outer periphery of a dowel pin.

The 12 and 13 show as further embodiments that it is also possible, a plurality of quick-release cylinders in three mutually perpendicular directions on a processing tower 35 to assemble and these with the help of gauges 37 . 38 . 39 align.

With the dial gauge 37 Will with weakly tightened screws 8th each the lid 6 of in-plane quick release cylinders 36 aligned and the same is done in the vertical direction with the dial gauge 39 ,

After the processing tower 35 a total of five sides arranged in a plurality of spaced grid arranged quick-release cylinders 36 carries, by means of appropriate gauges (also the dial gauge 38 at the top) the corresponding lid 6 of the quick release cylinder 36 aligned.

The particular advantage of the high-precision alignment of the cover lies in the fact that it depends on the precise machining of the quick-release plate 45 or the processing tower 35 or the machine table 4 does not arrive. It just needs to be taken care of that the lids 6 the quick release cylinder 36 be aligned highly accurately to a machine-fixed reference surface and secured secured in this position against high torsional forces. About the on the covers highly accurately and play-free positioned workpiece pallets and in turn play-free workpieces arranged so that a highly accurate, tilt-free and high torsional forces-resistant machining is possible.

This has the advantage that care must be taken only for the alignment of the lid for highly accurately machined workpieces and no longer has to be paid to the high-precision machining of a processing tower or a quick-release plate.

In the past, this even led to the fact that in a high-precision machining tower, where the alignment of the lid by means of a measuring machine had taken place, again an inaccuracy that was caused by the fact that the processing tower was spent with the high-precision aligned lids on a tilted or knocked machine, which a systematic error occurred on the machined workpieces. It was therefore not possible to provide the required accuracy when machining the workpieces.

This is the advantage of the invention, which provides that directly on the machine itself, the lid of the quick release cylinder 36 aligns and fixed in this aligned position highly secure against rotation, whereby an unwanted displacement of the lid and the workpiece pallet stored thereon even with strong processing forces 15 is avoided with certainty.
